    (b) A culvert or culverts shall be placed under the roadway or driveway;
    (c) The size and number of the culvert(s) shall be adequate to pass normal high water stages of the artificial water body being crossed. In no instance shall the culvert(s) provide a smaller cross-sectional area or hydraulic capacity than any upstream culvert;

    (g) The maintenance of the roadway, driveway or bridge shall continue to provide at least the same volume of discharge through the culvert(s).
    (2) If dewatering or channel flow diversion is performed, temporary fill dikes and dewatering discharges shall be installed and constructed so that no upstream flooding or impoundment occurs. Any temporary works shall be completely removed and all areas upstream and downstream from the crossing shall be restored to grades, elevations, and conditions existing before construction.
    (3) This general permit shall apply only to a maximum of two crossings on a given parcel of property, with a minimum distance of 500 feet between crossings.
